其次,針對氣閥振動信號的非平穩特點,本文採用了經驗模式分解法( empiricalmodedecomposition )對振動信號進行分析處理,使之成為若干個基本模式函數imf ( intrinsicmodefunction )和一個殘余量的線性組合。接著採用隨機子空間參數識別法對各個基本模式函數其進行結構參數識別,同時找出各種狀態的共同工作頻帶。The research indicated that, if the secondary combustion chamber was looked on as a controlled object, with the adjusting valve as a input, the pressure and the temperature of a selected point on the inside wall of the combustion chamber as outputs, then such controlled system would be a strongly non - linear, time varying system with number of random disturbances, which resulted in huge difficulty to build an analyzed mathematics model for the spray burning of the liquid fuel, so that classic control methods were all invalid
研究表明,若將rbcc發動機的二次燃燒室視為一個控制對象,同時以燃燒室內壁面取定點處的壓強、溫度和調節閥的開度為輸入輸出變量,則該系統將是輸入?輸出特性非線性很強、隨機干擾嚴重的復雜時變系統。這導致建立燃油噴霧燃燒具體模型的很大困難,從而宣告了經典控制方案的失效。According to the present problems and developing tendency of hydraulic turbine governor, four main issues of this field are studied in this paper. the content include hydraulic control system, frequency measurement unit, stability of the discrete control system, optimization of control parameters and self - adjusting pid control strategy based on fuzzy logic. several main achievement and results are obtained and shown as follows : the electric - hydraulic pilot valve driven by step - motor is firstly proposed, which solves the problem that the electric - hydraulic converter of hydraulic turbine governor hydraulic servo is prone to be stuck and blocked and improves the systemic stability greatly
本文根據水輪機調節領域存在的問題和發展趨勢,對水輪機調速器的液壓控制系統、頻率測量環節、離散調節系統穩定性與調節參數最優整定以及適應式參數自調整pid控制策略進行了研究,得到以下主要成果和結論:首次提出了採用步進電機驅動的步進式電液引導閥,從根本上解決了水輪機調速器電液隨動系統中存在的電液轉換元件發卡、堵塞問題,使電液隨動系統的可靠性大大提高。By measuring the differential pressure and using a regulated valve position to balance the flow rate to the same % dfr as the index valve, the next most favored branch can then be proportionally balanced as above and so on - finally after all the branches have been proportionally balanced the branch valves can then be proportionally balanced to each other
